Enable negotiation of the IPv6 network control protocol. (Enabled by

.It Ar disable-ipv6
Disable negotiation of the IPv6 network control protocol. Since every
IPv4 interface in an IPv6-enabled kernel automatically gets an IPv6
address assigned, this option provides for a way to administratively
prevent the link from attempting to negotiate IPv6. Note that
initialization of an IPv6 interface causes a multicast packet to be
sent, which can cause unwanted traffic costs (for dial-on-demand
interfaces).
